When you look at the calendar and it says 'July', you've left it late to start growing traditional photoperiod cannabis strains outdoors. It's still doable, but you're arguably cutting it a bit fine. Then there's the climate - depending on where you are in the northern hemisphere, you may be headed for some inclement weather.
But what about Early/Fast cannabis strains? Typically, these strains have shorter flowering times, enough to knock a couple of weeks of the wait. So depending on your positioning and your climate, you'll likely still have time to raise some of these. If not, there's still autoflowers and indoor growing, so all is not exactly lost. But if you can, wouldn't choosing seeds be so much easier if you knew the best early/fast strains on Seedsman? Well, we thought so, too!
What Are 'Earlies'?
'Earlies' or 'early versions' are selectively bred to mature faster than traditional strains. In cannabis cultivation, these fast-flowering strains are ready for harvest before the end of September, often categorized as 'fasts', 'quicks', or 'semi-full-term'. These varieties, maturing ahead of their standard photoperiod counterparts, are particularly advantageous in northern climates to avoid wet seasons and provide extended harvest windows. For a more comprehensive overview of early/fast cannabis, check out this article. In the meantime, here's a quick summary of the benefits of these cunning cultivars:
Benefits of Early Varieties
For Outdoor Cultivation
- Extended Harvest Window: Early varieties enable multiple harvests within a season, maximizing growing periods and increasing yield.
- Pest Resistance: Harvesting before peak pest seasons reduces the risk of crop damage.
- Mold Avoidance: Early harvests in regions with high humidity help prevent late-season mold issues, protecting the crop.
Genetic Selection for Quick Maturation
The essence of early varieties lies in their genetics. Through selective breeding, traits of quicker maturation become dominant, resulting in stable early strains. This process often involves crossing autoflowering varieties with photoperiod strains. Fast flowering can also be achieved by selecting individual plants with naturally shorter flowering times, such as certain kush or skunk varieties.

Shortened Growth Cycle
Early varieties progress from germination to maturity more quickly than standard strains. For example, fast-flowering cannabis plants can mature in as little as six weeks compared to the 8-15 weeks typical of traditional indica or sativa plants. This shortened growth cycle is achieved by triggering the flowering process earlier than usual, leading to a quicker harvest.
Cannabinoid and Terpene Profiles
While early varieties generally maintain similar cannabinoid and terpene profiles to standard strains, some subtle differences may exist. Early varieties can sometimes offer unique taste, aroma, and effects, enhancing the sensory experience for consumers.
Economic Implications
For commercial growers, early varieties provide a competitive edge by supplying fresh flowers to the market earlier, potentially commanding better prices. Multiple harvests in a season also lead to increased yields and profitability.
Adaptability to Climate and Soil
Early varieties often exhibit added adaptability to various climates and soil types. Some strains may be more resistant to specific diseases or tolerant of different environmental conditions, providing an additional layer of security for growers.
Conclusion
Fast-flowering cannabis varieties offer numerous advantages, from extended harvest periods and pest resistance to energy savings and rapid returns on investment. By understanding and selecting the right genetics, growers can optimize their operations for both indoor and outdoor cultivation, ensuring high-quality yields and economic benefits - without a notable compromise on returns.
